器件型号：DP83TC814S-Q1 大家好、我之前研究过待机和正常模式的配置。
每当我尝试将器件配置为待机模式时、请执行以下步骤：
//写入寄存器0x1F 位[7]-> 1. (直接访问)
//将 LPS_CFG3寄存器0x18C 写入0x0010，等于'10000b'。 (MMD1F 访问)
//读取 LPS_STATUS 寄存器0x18E 以检查 ETH PHY 的状态 (MMD1F 访问)
//在回读操作成功之前，尝试设置配置寄存器。
在下面的代码片段中、您可以找到相应的操作。 我认为寄存器读取和写入操作在很大程度上
void BusSleepMode::ConfigureETHPhytoStandbyMode(void)
{
uint16_t registerData = 1U;
registerData = registerData<<7U;
if(WRITE_STATUS_OK == Phy_write_register(0x1FU, registerData))
{
// Readback the register to check operation is successful or not.
if(READ_STATUS_OK == Phy_read_register(0x1FU, ®isterData))
{
if(1U == ((registerData>>7U) & 0x0001U ))
{
LOGI(&gETHNM_Log_ctx, "Write operation is successful for 0x1F");
while(contextInstanceSM.getETHPhyResetStatus() == false)
{
// Write to 0x18C '10000b' which is equal to 0x10
static_cast<void>(MMD1F_write_register(0x18CU, 0x0010U));
uint16_t readBack;
static_cast<void>(MMD1F_read_register(0x18EU, &readBack));
LOGD(&gETHNM_Log_ctx, "READBACK FOR STANDBY: ", readBack);
if(1U == ((readBack>>1U) & 0x0001U))
{
contextInstanceSM.setETHPhyResetConfigurationFlag();
LOGI(&gETHNM_Log_ctx, "Standby configuration is made. PHY is running in reset mode now.");
break;
}
else
{
LOGE(&gETHNM_Log_ctx, "Standby configuration is failed.");
}
std::this_thread::sleep_for(std::chrono::milliseconds(10));
}
}
}
}
else
{
LOGE(&gETHNM_Log_ctx, "Write register to 0x1F returned fail.");
}
}对于正常模式配置、我基本上遵循以下步骤：
//写入寄存器0x1F 位[7]-> 0。
//将 LPS_CFG3寄存器0x18C 写入0x0001，即等于"1b"。
//读取 LPS_STATUS 寄存器0x18E 以检查 ETH PHY 的状态
//直到状态为预期值，尝试设置。
void NetworkMode::ConfigureETHPhytoNormalMode(void)
{
uint16_t registerData = 0U;
registerData = registerData<<7U;
if(true == contextInstanceSM.getETHPhyResetStatus())
{
// Clear out the register data.
if( WRITE_STATUS_OK == Phy_write_register(0x1FU, registerData))
{
if(READ_STATUS_OK == Phy_read_register(0x1FU, ®isterData))
{
if(0U == ((registerData>>7U) & 0x0001U ))
{
LOGI(&gETHNM_Log_ctx, "Read operation is successful for 0x1F. Bit is cleared.");
while(contextInstanceSM.getETHPhyResetStatus() == true)
{
// Write 0x18C to '1b' to set the normal mode.
static_cast<void>(MMD1F_write_register(0x18CU, 0x0001U));
uint16_t readBack;
static_cast<void>(MMD1F_read_register(0x18EU, &readBack));
LOGD(&gETHNM_Log_ctx, "READBACK FOR NORMAL: ", readBack);
if(1U == ((readBack>>2U) & 0x0001U))
{
contextInstanceSM.clearETHPhyResetConfigurationFlag();
LOGI(&gETHNM_Log_ctx, "Reset configuration is cleared. PHY is running in normal mode.");
break;
}
else
{
LOGE(&gETHNM_Log_ctx, "Reset configuration is failed.");
}
std::this_thread::sleep_for(std::chrono::milliseconds(10));
}
}
}
}
else
{
LOGE(&gETHNM_Log_ctx, "Write register to 0x1F returned fail.");
}
// Set the link status up by using ioctl functions
changeLinkStatus("eth0");
changeLinkStatus("vlan1");
}
}在这些配置后、每当我切换到正常模式时、我就会在2秒内无法发送数据。
这些配置是否正确、或者我是否需要在其他地方检查？
